Solution for (z-2)(z+2z+4)= equation:


Simplifying
(z + -2)(z + 2z + 4) = 0

Reorder the terms:
(-2 + z)(z + 2z + 4) = 0

Reorder the terms:
(-2 + z)(4 + z + 2z) = 0

Combine like terms: z + 2z = 3z
(-2 + z)(4 + 3z) = 0

Multiply (-2 + z) * (4 + 3z)
(-2(4 + 3z) + z(4 + 3z)) = 0
((4 * -2 + 3z * -2) + z(4 + 3z)) = 0
((-8 + -6z) + z(4 + 3z)) = 0
(-8 + -6z + (4 * z + 3z * z)) = 0
(-8 + -6z + (4z + 3z2)) = 0

Combine like terms: -6z + 4z = -2z
(-8 + -2z + 3z2) = 0

Solving
-8 + -2z + 3z2 = 0

Solving for variable 'z'.
